Bobby I am going to apologize one more time for the wrong block..... You gave us the info on the mower deck not the Engine Model number..... If you would have posted the engine numbers we would have known right away what you needed.....
I wish you would have put a picture up of your mower at the start of your thread..... On here we go by what people tell us.... Some people make a video and post it....
Like everyone says on here, we are not there with you to see what you have or hear a problem....... You wanted a replacement and your engine ran great.... But smoked a lil bit . I advised you to put a heavier oil in it for a temporary fix.
In post 19 you posted a link to engine that was 8.5 gross torque with a 7/8 dia shaft 3 5/32 long...... The block you got has the same measurements.....
Like I said earlier one of us will need that block soon.... Heck if I had the money now I would take it off your hands..... I just made a 600 dollar order from my wholesale parts warehouse so that blew my wallet wide open......
Your local shop has used parts to put on that block.... That block doesn't need many parts so it will be worth it and you are gonna have a new stronger engine, for cheaper than rebuilding your old one....
Plus Tard Mon Ami ..........
